System and method to authenticate contact center agents by a reverse authentication procedure

ABSTRACT

An authentication system to validate the authenticity of call center agents by using a reverse authentication procedure. The authentication system includes a verification module that verifies the authenticity of agents calling from the call center. The verification module retrieves reference answers in response to the user-provided query questions from a media server. The media server may be located inside the enterprise network. These reference questions and their corresponding reference answers are provided by users when registering with the enterprise network.

BACKGROUND

Field

Embodiments of the present invention generally relate to a system and method to authenticate contact center agents of an enterprise and particularly to a system and method to authenticate contact center agents by a reverse authentication procedure.

Description of Related Art

Contact centers are employed by many enterprises to service inbound and outbound contacts from customers. A primary objective of contact center management is to ultimately maximize contact center performance and profitability. An ongoing challenge in contact center administration is monitoring and optimizing contact center efficiency usage of its available resources. The contact center efficiency is generally measured by metrics such as Service Level Agreement (SLA), Customer Satisfaction (CSAT), and match rate. Contact center resources may include, agents, communication assets (e.g., number of voice trunks, number and bandwidth of video trunks, etc.), computing resources (e.g., a speed, a queue length, a storage space, etc.), and so forth.

Service level is one measurement of the contact center efficiency. Service level is typically determined by dividing the number of contacts accepted within a specified period by the number accepted plus number that were not accepted, but completed in some other way (e.g., abandoned, given busy, canceled, flowed out). Service level definitions may vary from one enterprise to another.

Match rate is another indicator used in measuring the contact center efficiency. Match rate is usually determined by dividing the number of contacts accepted by a primary skill level agent within a period of time by the number of contacts accepted by any agent in a queue over the same period. An agent with a primary skill level is one who typically may handle contacts of a certain nature more effectively and/or efficiently as compared to an agent of lesser skill level. There are other contact center agents who may not be as proficient as the primary skill level agent, and those agents are identified either as skill level agents or backup skill level agents. As can be appreciated, contacts received by a primary skill level agent are typically handled more quickly and accurately or effectively (e.g., higher revenue attained) than a contact received by a secondary or even backup skill level agent. Thus, it is an objective of most contact centers to optimize match rate along with the service level.

In addition to service level and match rate performance measures, contact centers use other Key Performance Indicators (“KPIs”), such as revenue, estimated, actual, or predicted wait time, average speed of answer, throughput, agent utilization, agent performance, agent responsiveness and the like, to calculate performance relative to their Service Level Agreements (“SLAs”). Operational efficiency is achieved when the KPIs are managed near, but not above, SLA threshold levels.

Throughput is a measure of the number of calls/contact requests or work requests that may be processed in a given amount of time. Agent utilization is a measure of how efficiently the agents' time is being used. Customer service level is a measure of the time customers spend waiting for their work to be handled. Company contact center customers wish to provide service to as many requests as possible in a given amount of time, using the least number of agents to do so, and minimizing the wait time for their customers that may increase the Service Level Agreement (SLA) of the contact center. Further, the contact center may also have to maintain the Customer Satisfaction (CSAT) metrics in order to maintain the KPIs of the contact center. For this purpose, agents may have to maintain the quality of services provided to the customers through multimedia (e.g., voice calls, video calls, emails, etc.).

In today's communicatively connected world, the massive growth in information has been the key to the sustainable growth of the human race. To keep this sustainable growth intact, security of the information transferring from one point to another point holds primal importance. These days, hackers continuously try to steal crucial information from various enterprises such as financial institutions, insurance companies, health care service providers, consumer goods companies and so on. The modus operandi of these peoples are simple which is they pose as fake contact center agents on behalf of these enterprises, gather somehow some very basic information about the account holders who are having any kind of accounts at those enterprises and then trick those unsuspecting users to divulge a plurality of crucial personal information about themselves. Most of the times peoples who receive such calls from these fake agents do not have any way to verify the authenticity of the callers.

Further, to reduce costs of operating a contact center on their own, many enterprises outsource the responsibilities of running contact centers with smaller firms. In this way, a plurality of crucial user-related information is shared with many other people, some of whom may have ill intent. Due to this, users may also be hesitant to disclose their crucial personal information, which in turn may hamper the overall functionality of the contact center. In the initial five months of 2014, some of the United Kingdom's (UK's) top financial institutions have reported a combined loss of over £ 21 million due to multiple phishing attacks. Phishing attacks are the most common fraud attack in today's financial world, in which fake people pose as contact center agents of a financial institution, contact unsuspecting users having accounts with those financial institutions and trick those users to divulge their personal information. According to another statistic, for every 2000 phishing attacks, every person on an average loses more than £ 10,000.

Common conventional techniques to detect financial fraud include: verifying the caller by installing calling line identification (CLI); periodically receiving feeds from service providers; installing an app on a smartphone that can detect a bogus caller. Though each of these disclosed techniques may help to differentiate between an original contact center agent and a bogus agent, they are still not fully fraud proof. For example, hackers may easily hide their bogus calling numbers even from CLI or true caller so that they cannot be detected by those techniques. None of the current conventional techniques provide an approach by which a person who is receiving such a call from a bogus agent actually can validate the authenticity of the callers.

Thus, there is a need for a system and method to validate the authenticity of contact center agents to eliminate the risks of fraud.

SUMMARY

Embodiments in accordance with the present invention provide a system to authenticate the identities of the contact center agents. The authentication system maybe located inside a contact center server. The system includes a verification module configured to provide reference answers to at least one reference question asked by the user to validate the authenticity of the contact center agent. The user may provide the reference questions and their corresponding reference answers while registering with the enterprise network, and the reference questions and their corresponding reference answers are stored in a media server. The verification module fetches the reference answers from the media server and provides them to the user. A reference answer may also be referred to herein as a pre-recorded secret authentication message. “Secret” as used throughout herein may refer to something that is kept private and is known and/or verifiable only by an intended person. For example, a secret authentication message would be a message that only an intended person would know and can verify (e.g., because that person supplied the message).

Embodiments in accordance with the present invention further provide a computer-implemented method for authenticating identities of agents of an enterprise contact center. The method includes playing a pre-recorded secret authentication message to the user before initiating a conversation; verification done by the user about the authenticity of the caller after hearing the pre-recorded secret authentication message; and accepting the agent generated outbound call from the enterprise call center associated with the enterprise network by the user.

Embodiments in accordance with the present invention further provide a computer-implemented method for authenticating identities of agents of an enterprise contact center. The method includes playing a pre-recorded secret authentication message to the user before initiating a conversation wherein the pre-recorded secret authentication message may be generated by the user itself during registration with the enterprise network; verification done by the user about the authenticity of the caller after hearing the pre-recorded secret authentication message; and accepting the agent generated outbound call from the enterprise call center associated with the enterprise network by the user.

Embodiments of the present invention may provide a number of advantages depending on its particular configuration. The present application provides a system and a method to authenticate contact center agents by a reverse authentication procedure. The present application further provides two options for the reverse authentication procedure for the users to authenticate the calling agents. The first option is listening to a pre-recorded secret authentication message that was recorded and stored in an enterprise server by the user itself while registering with the enterprise network. The second option is to ask questions and retrieve the correct answers from the contact center, in which the questions and answers were recorded by the user when registering with the enterprise network. Further, the present application utilizes reverse authentication procedures to reduce the risk of receiving fraudulent calls from imposters posing as contact center agents and trying to steal information from unsuspecting people.

These and other advantages will be apparent from the present application of the embodiments described herein.

A module that performs a function also may be referred to as being configured to perform the function, e.g., a data module that receives data also may be described as being configured to receive data. Configuration to perform a function may include, for example: providing and executing computer code that performs the function; providing provisionable configuration parameters that control, limit, or enable capabilities of the module (e.g., setting a flag, setting permissions, setting threshold levels used at decision points, etc.); providing a physical connection, such as a jumper to select an option, or to enable/disable an option; attaching a physical communication link; enabling a wireless communication link; energizing a circuit that performs the function (e.g., providing power to a transceiver circuit in order to receive data); and so forth.

The term “switch” or “server” as used herein should be understood to include a Private Branch Exchange (PBX), an ACD, an enterprise switch, or other type of communications system switch or server, as well as other types of processor-based communication control devices such as media servers, computers, adjuncts, etc.

FIG. 1A shows an illustrative embodiment of the present invention. A contact center 100 comprises a server 110, a set of data stores or databases 114 containing contact or customer related information, resource or agent related information and other information that may enhance the value and efficiency of the contact processing, and a plurality of servers, namely a voice mail server 118, an Interactive Voice Response unit (e.g., IVR) 122, and other servers 126, a switch 130, a plurality of working agents operating packet-switched (first) communication devices 134-1-N (such as computer work stations or personal computers), and/or circuit-switched (second) communication devices 138-1-M, all interconnected by a Local Area Network (LAN) 142, (or Wide Area Network (WAN)). In another embodiment of the present invention, the customer and agent related information may be replicated over multiple repositories.

The servers may be connected via optional communication lines 146 to the switch 130. As will be appreciated, the other servers 126 may also include a scanner (which is normally not connected to the switch 130 or Web Server), VoIP software, video call software, voice messaging software, an IP voice server, a fax server, a web server, an email server, and the like. The switch 130 is connected via a plurality of trunks to a circuit-switched network 150 (e.g., Public Switch Telephone Network (PSTN)) and via link(s) 154 to the second communication devices 138-1-M. A security gateway 158 is positioned between the server 110 and a packet-switched network 162 to process communications passing between the server 110 and the packet-switched network 162. In an embodiment of the present invention, the security gateway 158 (as shown in FIG. 1A) may be a G700 Media Gateway™ from Avaya Inc., or may be implemented as hardware such as via an adjunct processor (as shown) or as a chip in the server 110.

The switch 130 and/or server 110 may be any architecture for directing contacts to one or more communication devices. In some embodiments of the present invention, the switch 130 may perform load-balancing functions by allocating incoming or outgoing contacts among a plurality of logically and/or geographically distinct contact centers. Illustratively, the switch 130 and/or server 110 may be a modified form of the subscriber-premises equipment sold by Avaya Inc. under the names Definity™ Private-Branch Exchange (PBX) based ACD system, MultiVantage™ PBX, Communication Manager™, S8300™ media server and any other media servers, SIP Enabled Services™, Intelligent Presence Server™, and/or Avaya Interaction Center™, and any other products or solutions offered by Avaya or another company. Typically, the switch 130/server 110 is a stored-program-controlled system that conventionally includes interfaces to external communication links, a communications switching fabric, service circuits (e.g., tone generators, announcement circuits, etc.), memory for storing control programs and data, and a processor (i.e., a computer) for executing the stored control programs to control the interfaces and the fabric and to provide ACD functionality. Other types of known switches and servers are well known in the art and therefore not described in detail herein.

The first communication devices 134-1-N are packet-switched and may include, for example, IP hardphones such as the 4600 Series IP Phones™ from Avaya, Inc., IP softphones such as an IP Softphone™ from Avaya Inc., Personal Digital Assistants (PDAs), Personal Computers (PCs), laptops, packet-based H.320 video phones and conferencing units, packet-based voice messaging and response units, packet-based traditional computer telephony adjuncts, peer-to-peer based communication devices, and any other communication device.

The second communication devices 138-1-M are circuit-switched devices. Each of the second communication devices 138-1-M corresponds to one of a set of internal extensions Ext-1-M, respectively. The second communication devices 138-1-M may include, for example, wired and wireless telephones, PDAs, H.320 videophones and conferencing units, voice messaging and response units, traditional computer telephony adjuncts, and any other communication devices.

It should be noted that the embodiments of present invention do not require any particular type of information transport medium between switch, or server and first and second communication devices, i.e., the embodiments of the present invention may be implemented with any desired type of transport medium as well as combinations of different types of transport channels.

The packet-switched network 162 may be any data and/or distributed processing network, such as the Internet. The packet-switched network 162 typically includes proxies (not shown), registrars (not shown), and routers (not shown) for managing packet flows.

The packet-switched network 162 as shown in FIG. 1A is in communication with a first communication device 166 via a security gateway 170, and the circuit-switched network 150 with an external second communication device 174.

In one configuration, the server 110, the packet-switched network 162, and the first communication devices 134-1-N are Session Initiation Protocol (SIP) compatible and may include interfaces for various other protocols such as the Lightweight Directory Access Protocol (LDAP), H.248, H.323, Simple Mail Transfer Protocol (SMTP), IMAP4, ISDN, E1/T1, and analog line or trunk.

It should be emphasized that the configuration of the switch 130, the server 110, user communication devices, and other elements as shown in FIG. 1A is for purposes of illustration only and should not be construed as limiting embodiments of the present invention to any particular arrangement of elements.

Further, the server 110 is notified via the LAN 142 of an incoming service request or work item by the communications component (e.g., switch 130, a fax server, an email server, a web server, and/or other servers) receiving the incoming service request as shown in FIG. 1A. The incoming service request is held by the receiving telecommunications component until the server 110 forwards instructions to the component to forward or route the contact to a specific contact center resource, such as the IVR unit 122, the voice mail server 118, and/or first or second telecommunication device 134-1-N, 138-1-M associated with a selected agent.

FIG. 1B illustrates at a relatively high-level hardware abstraction a block diagram of a server such as the server 110, in accordance with an embodiment of the present invention. The server 110 may include an internal communication interface 151 that interconnects a processor 157, a memory 155 and a communication interface circuit 159. The communication interface circuit 159 may include a receiver and transmitter (not shown) to communicate with other elements of the contact center 100 such as the switch 130, the security gateway 158, the LAN 142, and so forth. By use of programming code and data stored in the memory 155, the processor 157 may be programmed to carry out various functions of the server 110.

Although embodiments are discussed with reference to client-server architecture, it is to be understood that the principles of embodiments of the present invention apply to other network architectures. For example, embodiments of the present invention apply to peer-to-peer networks, such as those envisioned by the Session Initiation Protocol (SIP). In the client-server model or paradigm, network services and the programs used by end users to access the services are described. The client side provides a user with an interface for requesting services from the network, and the server side is responsible for accepting user requests for services and providing the services transparent to the user. By contrast in the peer-to-peer model or paradigm, each networked host runs both the client and server parts of an application program. Additionally, embodiments of the present invention do not require the presence of packet- or circuit-switched networks.

The term “switch” or “server” as used herein should be understood to include a Private Branch Exchange (PBX), an ACD, an enterprise switch, an enterprise server, or other type of telecommunications system switch or server, as well as other types of processor-based communication control devices such as media servers, computers, adjuncts, etc.

Referring to FIG. 2, one possible configuration of the server 110 is depicted. The server 110 is in communication with a plurality of customer communication lines 200 a-y (which can be one or more trunks, phone lines, etc.) and agent communication line 204 (which can be a voice-and-data transmission line such as the LAN 142 and/or a circuit switched voice line). The server 110 can include Avaya Inc.'s an Operational Analyst™ (OA) with On-Line Analytical Processing (OLAP) technology, or a Call Management System (CMS) 228 that gathers profile of agents of the contact center and monitors current status of the agents and parameters of the received work requests. OA and CMS will hereinafter be referred to jointly as CMS 228.

As can be seen in FIG. 2, included among the data stored in the server 110 is a set of contact queues or work request queues 208 a-n and a separate set of agent queues 212 a-n. Each work request queue 208 a-n corresponds to a different set of agent queues, as does each agent queue 212 a-n. Conventionally, a contact is prioritized and either is enqueued in individual ones of the contact queues 208 a-n in their order of priority or is enqueued in different ones of a plurality of contact queues 208 a-n that correspond to a different priority. Likewise, each agent's queue 212 a-n is prioritized according to his or her level of expertise or skill in that queue, and an agent is either enqueued in one of an individual agent queues 212 a-n in their order of expertise level, or is enqueued in a different one of a plurality of agent queues 212 a-n that correspond to a queue, and each queue corresponds to a different expertise level.

Included among the control programs in the server 110 is a work request vector 216. Contacts incoming to the contact center are assigned by the work request vector 216 to different work request queues 208 a-n based upon a number of predetermined criteria, including customer identity, customer needs, contact center needs, current contact center queue lengths, customer value, and the agent skill that is required for the proper handling of the contact. Agents who are available for handling work requests are assigned to the agent queues 212 a-n based upon the skills that they possess. An agent may have multiple skills, and hence may be assigned to multiple agent queues 212 a-n simultaneously. Furthermore, an agent may have different levels of skill expertise (e.g., skill levels 1-N in one configuration or merely primary skill levels and secondary skill levels in another configuration), and hence may be assigned to different agent queues 212 a-n at different expertise levels.

In one configuration, the contact center is operated by a contract operator (e.g., a supervisor or a manager of the contact center), and each of the work request queues 208 a-n, and possibly each of the agent queues 212 a-n, corresponds to a different client. Each client can have a separate service level agreement or other type of performance measurement agreement with the contract operator regarding performance expectations, goals, requirements or specifications for the client's respective queue(s). The service level agreement can set forth penalties, such as financial penalties, for failing to comply with the service level agreement's requirements.

Further, embodiments in accordance with the present invention may include, among the programs executing on the server 110, an agent selector 220 and an agent authentication system 224. The agent selector 220 and the agent authentication system 224 are stored either in the main memory or in a peripheral memory (e.g., disk, CD ROM, etc.) or some other computer-readable medium of the contact center 100. Further, the agent selector 220 monitors the occupants of the work item and agent queues 208 a-n and 212 a-n, respectively, and contact center objectives, rules, and policies and assigns agents to service work items.

The agent selector 220 distributes and connects these work items to communication devices of available agents based on the predetermined criteria noted above. When the agent selector 220 forwards a contact (or first work item) to an agent, the agent selector 220 also forwards customer-related information from the database 114 to the agent's desktop or computer work station for previewing and/or viewing (such as by a pop-up display) to enable the agent for providing better services to the customer. Depending on the contact center configuration, the agent selector 224 may reallocate the work items to the agents of the contact center 100. The agents process the contacts or work items sent to them by the agent selector 220.

According to an embodiment of the present invention, the agent authentication system 224 is configured to validate the authenticity of the calling agents. The agent authentication system 224 includes a certain module, such as, but is not restricted to, a verification module 226. In some embodiments, the verification module 226 may be implemented by one or more software processes running on the server 110. The server 110 may implement one or more software processes by use of the processor 157 being suitably programmed by use of software instructions stored in the memory 155 coupled to the processor 157.

The verification module 226 may validate the authenticity of the agents the contact center 100 according to an embodiment of the present invention. The type of the call, i.e., whether the call made by an agent is a voice call, a video call, a text message, an email, an instant messaging, a Voice over Internet Protocol (VoIP), and so forth.

According to an embodiment of the present invention, FIG. 3 illustrates a representation about a possible implementation scenario of forming a communication session path in between a user 302, a contact center 100 which includes a server 110, a contact center agent 308 and a media server 306. The contact center 100, the contact center agent 308 and the media server 306 may all be located inside an enterprise network 304. The server 110 may include an agent authentication system 224 where the agent authentication system 224 may also include a verification module 226.

During registration with the enterprise network 304, the user 302 may record a secret authentication message, which may also be referred to as a reference message. Further, the user 302 may also record at least one security question and its corresponding answer. The corresponding answer may also be referred to as a reference answer. The enterprise network 304 may store in the media server 306 information related to user 302 along with the secret authentication message and the security questions and their answers.

When the user 302 receives a call from the contact center agent 308 of the contact center 100, the server 110 automatically fetches the pre-recorded secret authentication message from the media server 306 and plays it for the user 302 to hear. After hearing the pre-recorded secret authentication message, which the server 110 played for the user 302, the user 302 is more assured that the contact center agent 308 who is calling on behalf of the enterprise network 304 is genuine. After verification, the user 302 may accept the call received from the contact center agent 308 and continue discussion. The details of the call may include, a type of call, i.e., whether the call received by the user 302 from the agent 308 is a voice call, a video call, a text message, an email, an instant message, a Voice over Internet Protocol (VoIP), and so forth.

Assuming user 302 recorded at least one security question and its related answer, and that they were saved in media server 306, contact center 100 may route the call to verification module 226, either automatically or on request of user 302. Verification module 226 is located inside agent authentication system 224. During verification, user 302 may ask a pre-recorded question, which is routed to verification module 226. Verification module 226 may fetch the corresponding pre-recorded answer from media server 306 and provide the pre-recorded answer back to user 302. If user 302 hears the expected answer, user 302 will be more assured that contact center agent 308 is an agent representing enterprise network 304.

The recorded secret authentication message provided by user 302 during registration may at least be one of a secret phrase or a secret number. User 302 may enter the secret phrase or the secret number during registration with the enterprise network 304 at least by a text message or a voice message.

If the recorded secret authentication message is a voice message, the agent authentication system 224 located inside the server 110 may fetch the voice message and delivers it to the user 302. If the secret authentication is a text message, then the agent authentication system 224 may fetch the text messages, converts the text message to speech messages and then deliver them to the user 302 for the authentication purpose.

According to an embodiment of the present invention, FIG. 4 illustrates a representation about a possible implementation scenario of forming a communication session path in between a user 402, a contact center 100 which may include a server 110, a contact center agent 410 and a media server 406. The contact center 100 and the media server 406 may be located in a separate authentication server 404. The authentication server 404 may be controlled by a separate agency that provides authentication services. The contact center agent 410 may be located inside an enterprise network 408.
